PEAR.Functions.FunctionCallSignature broken when closure uses return types

[Majkl578]

The following code is considered as invalid:

<?php

array_filter(
    [1, 2],
    function ($i) : bool {
        return $i === 0;
    }
);

Although the indenation is correct, the error is generated: Multi-line function call not indented correctly; expected 4 spaces but found 8. Note that when you remove : bool, it works fine.
Affects phpcbf as well (changes code to invalid format).
